Other Unixes - An experimental sub-forum where users can discuss and ask questions about Unix and Unix-like systems that are not Linux. For example, users would discuss the following systems here, *BSD, Solaris, OpenIndiana, HP-Unix, Haiku, BeOS, etc.

Android - Android is Linux, but not very many people are aware of that. Having a whole category for Android may increase the number of users on this site.

MeeGo - Again, some people are not aware this is a Linux system.

Linux Routers - Some Linux distro (like FREESO and Alpine Linux) are distros for routers, so a whole category should be dedicated to router and firewall Linux distros.
